Title: Improvements in or relating to dispersions of polymers
IPC: C08F220/28
Filed: 1954-12-21
Abstract: Aqueous polymeric dispersions which can be thickened by the addition of basically-acting substances are prepared by the aqueous emulsion polymerization of a mixture consisting to a preponderating extent of one or more methacrylic acid ether-esters of the general formula <FORM:0764021/IV(a)/1> in which x is 1 or a multiple thereof and R is an alkyl, aryl, aralkyl or alkoxy radical which may be attached to a neighbouring methylene group with ring formation, e.g. 2-methoxyethyl, 2 - ethoxyethyl, (2 - methoxy) - 2 - ethoxyethyl tetrahydrofurfuryl and diethylene glycol monomethyl ether methacrylates, and at least one acid group containing comonomer, e.g. acrylic, methacrylic and vinyl sulphonic acids, and optionally one or more other copolymerizable compounds, e.g. acrylonitrile, butyl acrylate, butyl methacrylate and a fatty alcohol ester of methacrylic acid.  In an example a mixture of monomers and ammonium persulphate is added gradually to a heated aqueous medium containing a condensation product of a fat acid and sodium hydroxyethyl sulphonate as an emulsifying agent, polymerization being complete after two hours.  Suitable basic substances for thickening the dispersions are ammonia, diethanolamine and triethanolamine.  The aqueous dispersions may be used for coating paper or leather, or as a stove-lacquer containing titanium dioxide as a pigment.

Title: Oxidation-resistant carbon
IPC: C04B41/85
Filed: 1965-08-31
Abstract: The invention comprises a carbon body containing calcium aluminium oxyphosphate.  It may be prepared by impregnating the body or applying to it an acid aqueous solution containing calcium aluminium oxyphosphate, and drying the body to remove solvent therefrom. Alternatively calcium, aluminium and oxyphosphorus containing reactants in acid solution are applied and the treated body is heated.  Calcium containing reactants may be tricalciumphosphate, monocalcium phosphate, calcium pyrophosphate, dicalcium phosphate, tetracalcium orthophosphate, decacalcium orthophosphate, ammoniumcalcium dimetaphosphate, calcium chloride, calcium bromide, calcium fluoride, calcium carbonate, calcium oxide, calcium aluminate, calcium nitrate, calcium acetate or elemental calcium. Aluminium containing reactants may be tribasic aluminium phosphate, monobasic aluminium phosphate, dibasic aluminium phosphate, aluminium pyrophosphate, aluminium acid phosphate, aluminium metaphosphate, aluminium chloride, aluminium bromide, aluminium fluoride, aluminium oxide, aluminium carbonate, aluminium acetate, calcium aluminate, or elemental aluminium.  The oxyphosphorus reactant may be an oxyacid of phosphorus (especially ortho-phosphoric acid) anhydrides of these acids and mono and diammonium salts of these acids.  Preferably CaO Al2O3 and P2O5 or calcium aluminate an P2O5 are used and the temperature may be a little over room temperature (24 DEG  C.) or 100-105 DEG  C. The reaction mixture is used to impregnate a carbon article to improve its oxidation resistance.  The body may be graphite, amorphous or "gas-baked" carbon and the impregnating solution may be used in an amount of 1-10% by weight of the body. The impregnation is effected by placing the body in an evacuated container, brushing, spraying or soaking with the solution and then pressurizing the container.  This cycle may be repeated and is followed by drying at 100-110 DEG  C. for 4 to 24 hours and naking at 250-500 DEG  C. for 4 hours.

Abstract: 862,379. Neutron detectors. SlEMENSSCHUCKERTWERKE A.G. Nov. 21, 1958 [Nov. 22, 1957], No. 37546/58. Class 39(4). Neutron detecting apparatus for use in a nuclear reactor comprises a neutron detector shielded from gamma rays and disposed in association with a moderator substance of large diffusion length for slowing down neutrons, with a reflector substance disposed adjacent the moderator, and with a neutron absorber disposed adjacent the reflector. In Fig. 1 the detector 1 bears against a gamma ray absorbing plate 5, for example of bismuth, attached to the wall 6 of the reactor, and is embedded in a moderator 2, for example heavy water, carbon, or beryllium, surrounded by a reflector layer 3, for example water, paraffin, or polyethylene, and a neutron absorbing layer 4 which may be a coating of boron. A plug 7 at the rear of the detector is provided with passages to allow electrical connections to pass through to the detector and allows the detector to be changed. In a modification, Fig. 3 (not shown), the layers 2, 3 and 4 completely surround the detector 1. In a further modification, Fig. 5 (not shown), a number of detectors are each surrounded by layers 2 and 3 and are surrounded by a common layer 4 which is surrounded by a further layer, for example of iron, which absorbs both neutrons and gamma rays. The number of detectable neutrons can be increased by reducing the thickness of the wall of the reactor or by reducing the thickness of the reflector of the reactor in the vicinity of the detector. If the reflector of the reactor is of graphite, the graphite may be omitted near the wall where detectors are to be placed, Fig. 4 (not shown); if the reflector is heavy water, means may be provided for displacing heavy water in the vicinity of the detectors when measurements are to be made. In another arrangement, Fig. 2, the reactor is provided with a re-entrant tube 9 in which is placed the detector 1, surrounded by a gamma ray shield 5, a moderator 2, and a reflector 3 covered by a neutron absorber 4.
